This map shows the Tribal Lands and Shellmounds of the San Francisco Bay Region.

Bay Area Tribal Lands & Shellmounds; created by Gabriel Duncan, based on Nelson(1909) Shellmounds Maps; Base map is “Watercolor” by Stamen Designs.

Most maps of this area show “Language Groups”. I think it’s important to specifically mention that Language Groups are not Tribes, and do not accurately reflect the culture or specific Identity of a Tribal Group, or “Triblet”.
